CAR VENTILATOR.

Application led December 27, 1926. Serial No. 157,086.

This invention relates to car ventilators, having reference more particularly to ventilators used on cars for the transportation of poultry and other live stock.

Heretofore, so far as I am aware, ventilators of this type have consisted of hinged shutters guarding opening in the side walls of the clearstory between the running board and the roof, and opening in an out-ward direction. Where, as is common in poultry cars, screens are also employed under the ventilator shutters, this construction has required-the attendant to climb onto the roof of the car in order to open or close the doors to the Ventilating openings.

One object of'my present invention is to provide an improved ventilator wherein the shut-ters shall be capable of being opened inwardly of the car and from the interior of the latter, making it unnecessary to disturb the outer screens. `Another object is to provide an inwardly opening shutter ventilator with means to shed rain and prevent the latter from beating in at the joint between the lower edge of the shutter and the car'lroof.

A further object of the invention is to provide simple and improved means for supporting the shutters in openposition from the roof of the clearstory.

Other objects and attendant advantages of the invention will be apparent to persons skilled in the art as the vsame becomes better understood by reference to the following detailedv description, taken in connection with the accompanying drawings wherein I have illustrated a practical and approved embodiment of the invention, and in which- Fig. 1 is a vertical cross-section through the roof and clea-rstory of a car equipped with my improvement, showing the shutters in closed position;

Fig. 2 is a similar view showing the shutters in open position;`

Fig. 3 is a longitudinal vertical section, broken out between its ends, on the line 3-3 of Fig. 1;

Fig. i is an outside elevation, broken out between its ends, of one side of the clearstory, showing the screens and the means for removably mounting the latter in place.

Referring to the drawing, 10 designates the principal roof rafters supporting the purlins 11, common rafters 12 and roof sheathing 13, all as common in freight car construction. 14 designates the rafters of turbing the outside screens, where the lat- 'ter are employed, and also preserving a raintight joint at the lower edges of the shutters. 17 designates the shutter board', to the inner side of which are secured a pair of U-shaped hinge members 18 formed at their Vupper ends withsuspension loops 18. These hinge loops are suspended from hing straps 19 conveniently attached to the under sides of the clearstory rafters 14 by the bolts 16. Each of the hinge straps 19 is so bent as to form outer and inner seats 2() and 21 for the hinge loop 18. Suspended from and-swiveled in a hanger bracket 22 (Fig. 2) attached to the ruiming board at a point about midway between the ends of an opposed pair of shutters is a T-bolt, conveniently bentl to form from heavy wire and comprising a. vertical stein 23 and a horizontal head 24. This T-bolt can be readily turned between a position wherein the head 24 extends longitudinally rof the car, as shown in Figs. 1 and 3. to a position wherein it extends transversely of the car, as shown l in Fig. 2.

To the inner side of each shutter 17 about midway between the hinge members 18 are transverse cleats 25, which serve to stiften the shutters and also serve as handles by which each shutter can be grasped, lifted, and its hinge loop 18 shifted between the seats and 21 of the hinge straps or brackets 19. In the closed position of the-shutters, the hinge loops 18 occupy the outer seats 20, as shown in Fig. 1. When it is desired to open the'shutters, the hinge loops are shifted into the inner seats 21, they are then swung inwardly towardy the central suspended T- bolts, and the heads 24 of the latter are then turned through a right angle so as to underlie and support the free edges of the shutters, in the manner clearly shown in Fig. 2.

fio

To provide a seal against rain, snow and cinders, I attach tothe inner edge of the roof sheathing 13 sheet-metal weather strips 26, Athe inneredges oi? whichV overhang the inner edges of the sheathing 13 and are bent upwardly, as shown at 26. The inner side of the lower edge oit' each shutter is beveled or chamfered, and attached thereto is a gutter shaped lip 27 that, in the closedposition of the shutter, internests with the upwardly inclined edge 26 et" the weather strip 26'. This provides an efficient joint 'for excluding moisture and dirt, and in no wise interferes withV the opening of the shutters, since when the latter are raised to shift them to the inner seats 21, the lower edge ont the shutter clears the upstandi'ng lip 26.

Guarding the openings opposite the re# spcctive shutters are screens 28, the rectangular frames 28v of which are removably mounted on and locked4 in place by yJlbolts 29 mounted in the r ipfters i4. It will' be observed that the described method and means oi mounting the shutters makes it possible to open and close the latter not only withoutdisturbing the screens but without the necessity of going outside the car which, in winter weather, is both disagreeable and dangerous.

I claiml. In a car ventilator, the combination with inwardly swinging shutters hinged at their yupper edges opposite the ventilating` openings of the clearstory, oi inverted' T`- shapedv members swivelingl'y attached to and depending from the roofv of the clearstory, the heads of said T-shaped members adapted, when disposed lengthwise of the car to permit full opening of said shutters, and when disposed crosswise ofthe car to underlie and support the free edges of said" shutters.

2; ln a car ventilator, in combination with the clearstory having ventilation openings in its sides,'hinge brackets attached to the underside of the clearstory rootl and eachformed with outer and inner seats, inwardly opening shutters disposed opposite the inner Sides of said openings, hinge straps attached to said shutters formed with loops engaged withl said outer seats when said shutters are 1n closed position and shiftalfileI `toengage with said inner seats when said shutters are formed withy outer and inner seats, shutters i having on their upper edgeshinge loops en-V gageable with' either of g said seats and' at their lower edges routwardly overlapping the lower edges of said openings whenthe shutters are closed, saidY shutters bein-g bodil'y shi'ftabl'e inwardly from closed position to transfer their hinge loops to-said inner seats and simultaneously clear their lower edges from the lower edges of said openings, and means suspended from 'the cl'earstory roof 'for supportingv said' shutters in inwardly raised position. f c

4. A structural combination as defined in claim 3' wherein the lapping edges ofthe shutters and the ventilating opening are formedt with interitting weather-strips separable under a bodily upward movement of the shutter in the operation of opening the latter.

5. In a car ventilator, in combination with the clearsteryv having Ventilating openings in its sides, shutters suspended from the roof `of the clearstory opposite the'inner sides of'sai'dv openings, outer and inner hinge sock ets spa-ced crosswise of the clearstory on which said shutters may be interchangeably hinged, said shutters in closedE position hanging from the outer sockets, and' in opened position hanging from the innerV sockets, and means operable `from thev interiorl of the car for4 supporting-said shutters in opened position.
